Every year when a new version of iOS is released there are always several problems, which is one of the reasons why some people wait for the first update in the hope of resolving whatever issue they have. It is for this reason why we are not surprised why there is an iOS 7 battery drain issue.
There is not only a iPhone 5 battery drain with iOS 7, but also iPhone 4S battery life problems as well, but don’t worry because there is a fix and it is one we have had to use time and again in the past. However, some of you might have forgot because it has been a year since you had to take this action.
As we said above the problem happens to thousands of people whenever there is a new iOS version, and all it really involves is that you do a clean install, although you need to make certain you have backed your iPhone up.
We have heard some cases where an iPhone battery is draining at a fast rate and fear it is hardware related. However, because it started directly after an update it is rather obvious it is software related. Thankfully I do not have to worry about an iPhone 5 battery life fix, but I already know several people who have had to do this.
In order to resolve these issues you first need to back your device up and then you will need to implement a clean install. This can either be done on iTunes in DFU mode where you need to keep your fingers on the sleep/wake button and home button and when you see the Apple logo appear keep hold of the Home button until you see a message on iTunes saying the phone is in recovery mode. You can also put your phone back to factory settings on the handset itself.
All you need to do is then connect your handset to iTunes, if you are not already connected and then let it download iOS 7, and following that also install your backup. Once you have taken these steps your issues should be a thing of the past, well that is the hope.
